Description
We would like to have an example for MicroProfile Metrics @Histogram annotation.
Here is a quick tutorial on MicroProfile Metrics if you are not aware of it:
https://www.tomitribe.com/blog/getting-started-with-microprofile-metrics/
Fork / clone the TomEE project from here:
https://github.com/apache/tomee
Example name should be mp-metrics-histogram, following the standard already in the project.
All the examples are in:
https://github.com/apache/tomee/tree/master/examples
See this example of @Counted for reference:
https://github.com/apache/tomee/tree/master/examples/mp-metrics-counted
See these two PRs for the diff for @Counted, it will help you see how simple it is:
https://github.com/apache/tomee/pull/203
https://github.com/apache/tomee/pull/207
What you have to do is:
1 - Create a method in the WeatherService class with @Histogram
2 - Have a WeatherServiceTest for the GET and OPTIONS scenarios of @Histogram
3 - Make sure you have tests for Prometheus and JSON formats
4 - Make sure all the tests pass
After that submit a PR and we'll review it.
